Preheat your oven to 350°F (175°C). Grease a 9x5-inch loaf pan with non-stick spray or butter.
In a large mixing bowl, cream together the softened butter and sugar until it becomes light and fluffy. This usually takes about 3-5 minutes.
Add the eggs one at a time, ensuring each one is fully incorporated before adding the next. Mix in the lemon juice and zest.
In a separate bowl, whisk together the flour, baking powder, baking soda, and salt. Gradually add the dry ingredients to the wet mixture, alternating with buttermilk, ensuring everything is well mixed.
Finally, gently fold in the poppy seeds.
Pour the batter into the loaf pan and smooth the top. Bake in the preheated oven for about 55-60 minutes or until a toothpick inserted in the center comes out clean.
Once baked, let the bread cool in the pan for 10 minutes before transferring it to a wire rack to cool completely.
Notes
This bread pairs wonderfully with a cup of tea or coffee, making it a perfect afternoon snack!
